Holy Innocents’ Episcopal School in Sandy Springs will kick off its $22.5 million One School Campaign at a reception and dinner Tuesday at the Atlanta History Center in Buckhead, it announced Tuesday in a news release. About 500 members of the school community are expected to attend the event, learning more about plans from Atlanta’s Collins Cooper Carusi Architects Inc., reviewing architectural renderings, and enjoying a special campaign video produced by broadcast students, faculty and staff.

The campaign, the largest in the school’s 54-year history, will fund the construction of the new Upper School Math and Science Building, renovations of the upper school’s Riley Building and Alumni Hall and an increase in the school’s endowment reserves.

“For more than 50 years, Holy Innocents’ has staked out a special place among Atlanta’s best schools,” said campaign Chairman Dave Stockert. “With this campaign, we build on a tradition of generosity and success, to be able to offer the best possible environment for the ongoing growth and development of our students.”

Stockert is a Holy Innocents’ parent, past chairman of the school’s board and president and CEO of Post Properties Inc.

Once complete, the school’s new 59,000-square-foot, three-story structure will become a campus flagship building. The top two floors will be outfitted with state-of-the-art classrooms and laboratories for math, science and technology programs, a new robotics laboratory and a media literacy suite for broadcast/journalism. The lower floor will house a communal dining hall that will seat 500 and a central kitchen to serve lower, middle and upper school students. Traffic flow in and out of campus will be improved, and Riley Building renovations will include adding a new entrance, repurposing classrooms, and updating the Malcolm Library.

As part of the overall plan, Holy Innocents’ has already renovated Alumni Hall, which now provides much-needed administrative offices and additional space for parking, meetings and school events.

The One School Campaign is already off to a strong start, Stockert said. Early supporters have contributed more than $15 million. The school hopes to secure the remaining $7.5 million during the 2013-14 school year, break ground in June and open new facilities for the 2015-16 school year.
